Title: Acoustic emission calibration instrumentation

Conference ·
OSTI ID:6972528

An automatic calibration instrument was developed to improve calibration accuracy of acoustic emission (AE) transducers by one order-of-magnitude over commercially available equipment. The instrument facilitates calibration by automatically displaying the maximum value of the stress used to produce AE calibration pulses and the AE pulse. Low-noise amplifiers and filters were also developed to improve the sensitivity of AE measurements by more than one order-of-magnitude over commercially available instruments; thus smaller signals may be detected in parts. 1 ref., 10 figs.
